I present Exhibit A, the new Reactor Flamaville in France. Construction took 17 years and 12 billion Euros.

Exhibit B, solar panels I can mount on my roof for a few thousand that run for 20 years without maintenance.

I rest my case.

EDIT: I did some estimating and figured that instead of building a NPR, France could have supplied around 500.000 households with solar and storage instead. That would be the populations of Lyon, Toulouse and Nice combined. And they would have around 65% of their power for free.
